Screen yellow where white should be
I haven't dropped my macbook or anything at all recently, and I'm experiencing a very peculiar issue. Last night everything was fine, but this morning I turned on my mac and the first thing that happened was that I saw vertical red lines all over the screen where white should be and flickering green dots a little bit on where black should be. After a couple of minutes all of that disappeared and instead it's now only yellow where white should be. Here are two screenshots, I'm not sure if you'll be able to see it as it may only appear on my screen, but please let me know:
I have the tools necessary to put apart my laptop (like the 3 basic screws) is there anything I can do? I don't want to go to the Apple Store just yet as their repair costs are probably expensive and I'm not sure about my warranty but I think it may have expired already, so I'll only go if I can't fix it myself. What exactly should I do?
Is dit een goede vraag?
